FLOOR-BEAM CONNECTION.

SPECIFICATION forming part of Letters Patent No. 407,066, dated July 16,1889.

Application filed May 16, 1889. Serial No. 310,996. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS EDWARDS, S12, of Chicago, in the county ofCook and State of Illinois, have invented a new and Improved Floor-BeamAnchor, of which the following is a full, clear, and exact description.

\Vith the ordinary form of floor-beam anchor, which is spiked to thebeam, it frequently happens that when buildings burn and the floor-beamsgive way the walls, which otherwise would stand, are torn down by theleverage brought to bear by the falling floorbeams. It is to overcomethis objection that I have designed the anchor forming thesubject-matter of'this application, the invention consisting,essentially, of an anchor formed with downwardly extending projectionsarranged to enter recesses formed in aplate that is arranged forconnection with the floorbeam, whereby the floor-beam is held to placeso long as it maintains a substantially horizontal position, but wherebythe beam will free itself from the anchor in case it is burned throughor breaks centrally, thus permitting the falling of the beam withoutinjury to the walls, all as will be hereinafter more fully explained.

Reference is to be had to the accompanyin g drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a central longitudinal sectional view of a floor-beam, aportion of its supporting-wall, and the anchor forming the subject.-matter of this application, the parts being represented as they appearwhen the floor-beam is in a horizontal position. Fig. 2 is a similarview, the parts, however, being represented as they appear when thefloor-beam has parted in the middle and is falling from the wall; andFig. 3 is a cross-sectional view on line a: 00 of Fig. 1.

In the drawings, 10 represents the wall of a building, and 11 afloor-beam. In the building-wall there is secured an anchor-bar12,formed with downwardly-extending projections'lS, and to which there isconnected a plate 11, said plate and the outer end of the bar 12 beingembedded in the outer wall 10 in the ordinary manner.

In the upper edge of the floor-beam 11, I secure a plate 15, that isheld to place by screws, as indicated in the drawings, or in any otherdesired manner, and in this plate I form a number of recesses 2, adaptedto receive the anchor projections 13.

In applying my anchor the parts are adj usted as represented in Fig. 1,and then should the beams 11 burn through or break they will drop fromthe anchor, as indicated in Fig. 2,thus leaving the walls 10 intact andin condition to receive new sets of floor-beams in case it should bedesired to rebuild the building.

Havingth us described my invention, I claim as new and desire to secureby Letters Patent The combination, with a floor-beam anchor formed withdownwardly-extending projections, of a plate formed with aperturesadapted to receive said projections and arranged for connection with"the floor-beam, substantially as described.
